Document Type and Number:
WIPO Patent Application WO2005023500
Kind Code:
A3
Abstract:
A method and apparatus are provided for manufacturing a thin-walled honeycomb ceramic substrate by extruding a plasticized ceramic batch material through a filter screen having wedge shaped filter wires to remove foreign particulate and agglomerated batch material. The filter wires are supported by a set of support wires attached substantially perpendicular to the filter wires. The support wires may also be wedge shaped. A cross section of the filter is shown in figure 7A. The filter screen of the present invention may have a wear resistant boride, nitride, or nickel-based coating at the surface of the screen.
